Duran is one of many ladies competing in season 8 of the NBC show. Prior to this season, the top female competitor has been former gymnast Kacy Catazaro, who made it all the way to the finals in season 6 and is back this year for another shot.

"Everyone told me I was too small, I was just a girl, I'd never make it up the wall," said Catanzaro, who stands 5' tall and weighs 100 pounds. "I did it because I believed in myself."

It took seven seasons for anyone, male or female, to claim the $1 million grand prize. Isaac Caldiero became the show's first winner last September when he conquered Stage 4 of Mt. Midoriyama in 26.14 seconds. This time around, Catazaro has hopes for becoming the first female winner.
